Unfortunately, there are no longer any repair tools for Big Sur or M1 for directories. Backup and restore is your most realistic option.

You could connect to an older computer (catalina or older) and run Disk Warrior, to repair it, but Disk Warrior is not available for any newer OS.

I'm on M1 Mac Big Sur and SoftRaid 6.1. OWC Thunderbay Raid5 in HFS+

Volume is mounting but at startup, I have a message saying "MacOS can't repair Thunderbay Volume". 

I can read but not write. What can I do ?
